Application filed October 17, 1913.

To all whom it may concern Be it known that I, NICOLAS JAMES Nroonamns, a subject of the King of Greece, residing at Bourgas, in the Kingdom of Bulgaria, shipping agent, have invented a new and useful Improvement in Apparatus for Loading Ships and for Discharging Cargo Therefrom, of which the following is a specification.

This invention relates to apparatus for loading ships and for discharging cargo therefrom, and to that class of discharging means wherein elevators furnished with buckets, carriers or the like are employed for raising the cargo from the hold of the vessel and discharging it upon a conveyer c-r chute on both sides of the ship.

The object of the present invention is to enable several elevators to be employed in one hold of the ship,'so that the cargo may be discharged from difierent parts ,of the hold simultaneously, thereby expediting the.

unloading and lo ading'of the ship.

According to this invention the heads of the elevators are supported upon two parallel shafts connected together by atransverse driving shaft the parallel shafts being disposed fore and aft of the vessel and mounted upon suitable supports, while the transverse shaft is driven by one engine or Figure 1 illustrates in transverse section,

the hold of a ship furnished with the improved means for discharging the cargo,

and Fig. 2 is a plan view-of the hatchway and shows the disposition of the elevators. v

Fig. 3 shows buckets and means of mounting them on the conveyer; Fig. 1 shows supporting members as applied to the conveyer chains for. supporting material in transit. Fig. 5 is a vertical section of the boot and adjacent parts. Fig. 6 is a plan of the same, and Fig. 7 shows an auxiliary chute to be used in connection with the boot.

In carrying out my invention I employ a plurality of elevators 1 the heads of which are mounted upon shafts 2, 3, arranged approximately parallel to each other and driven simultaneously by means of a transverse shaft 4;. In the construction illustrated the shafts 2, 3, are supported in bear- Specification of Letters Patent.

ings 2 3 mounted upon beams 2 3", which are placed upon the coamings 5 of the hatchway, while the shaft 4: is supported in bearings 4 mounted upon a beam 43 placed transversely of the beams 2", 3

The shaft 4B is furnished at each end with a bevel wheel 6,and these bevel wheels mesh respectively with bevel wheels 7,7 mounted upon the shafts 2' and 3. Midway of the shaft- 4 is a drum or pulley 8 which is driven from the winch 8 or by an engine. The shaft 4 is preferably of such a length as to be suitable for hatches of any width and the bevel wheels 6 as also the pulley 8 are slidably mounted thereon so that they may be adjusted to any desired position.

In the arrangement illustrated the shaft 2 is provided with one elevator and the wheels 1- at the upper ends of the elevators.

In a similar manner the bevel wheels 6 and the pulley 8 are adjustable along the shaft 4:.

The elevators comprise telescopic sides which, in the example illustrated consists of a series of metal tubes 9 within which slide At the lower. end of the elevatoris a boot 10 of the form shown in Figs. 5, 6 and 7, and transversely of this 'boot is mounted a shaft 11 to which the lower ends of the telescopic portions 9 of the elevator are attached. Upon the shaft is also mounted a pair of sprocket wheels 11 around which the elevator chains 12 pass.

On the top of the boot 10 and on that side where the chains 12 pass upward is provided a platform or support 10 'formed with recesses 10', 10?; the platformlO serving to support each package in position to be lifted by one pair of a series of arms 12 or like carriers adj ustably mounted upon the elevator chains 12 at suitable distances apart. In addition to the arms 12 the chains 12 may be provided with battens or pieces of wood 12 (Fig. 4:) which extend from the one chain to the other and which serve to form an apron to support the packages.

Instead of battens for supporting the packages any other suitable form of apron may be employed. The arms 12 are provided for use when the cargo comprises bales, barrels, packages or the hke, but when the cargo to be discharged consists of grain, coal, or

I pivoted link 13 to the said chains, this pivof the elevator. cargo is to be discharged the boot 10'is provided with a chute 10 (as shown in Fig. 7)

* otedlink serving to permit of the bucket passing over the upper sprocket wheels 1 Furthermore when bulk into which the coal, grain, or the like is fed and conveyed to the buckets. The cargo, whether bulk or otherwise, may, however,

be fed to the elevator by means of a conveyer, or by other'ineans, as is well known. The elevator chalns 12 may be built of links of any suitable construction, and in the construction illustrated the links are, by way of example, C-shape'd so that they may be readily connected together. To support-the chains intermediate of the ends of the elevator the latter may be provided with additional sprocket wheels 1 31 Fig. 1. i These additional wheels can be mounted between oppositely disposed outer tubes 9 of the telescopic sides of the elevators.

In the unloadingof a ship with my improved a pparatu's' the elevators lare suspended from the shafts 2 and 8,.(Fig; 2) which are supported upon the hatch coamings in the manner hereinbefore described,

and the telescopic sides 9 of the. elevators are extended so that the boot of each elevator'may be placed in the desired position. To fasten together the several lengths forming thetelescopic sides of the elevator, each rod or tube 9 mav be furnished with one or more bolts 9* the ends of which (Fig. 5) pass through slots 9 formed in the tubes 9.

The'shafts 2 and 3 are now driven simultaneously from the shaft 4: to operate the several elevators collectively and the cargo 7 to, be discharged is fed to the boot of each elevator, whence it is lifted by the elevator buckets or carriers and is thence discharged into alconveyer 1 1, Fig; 1, communicating with the quay or into a chute 15 communieating with a barge 16. It will thus be seen that by the employment of two'or more ele-.

vators worked simultaneously in one hold, that portion'of the cargo required for transit by land may be discharged directly on the quay, while'thatportion of the cargo required for transit by water may be dis:

Copies of this patent may be obtained for fivecents each, by addressingtthe (Commissioner of Patents, Y

charged into the barge. As the unloading of thevessel proceeds and the level 'of the cargo becomes lower in the hold the elevators are readily extended by drawing'out the telescopic sides and the chains of the elevators lengthened by the addition of links and buckets or carriers. In loading a. ship the elevators instead of extending into the hold'extend over the sides-of the ship, and as the packages are raised by the elevators" from the quay they aredelivered upon the heads of additional elevators of a similarkind which extend into the hold and which lower the packages. In the case of bulk cargo the coal, grain or the like is discharged directly' into the 'h'0ld fromthe heads of the lifting elevators, or into chutes.
